OBJECTIVETo determine human epidermal growth factor receptor 2 (HER2) status in breast carcinoma by the techniques of a fully automated immunohistochemistry (IHC) and fluorescence in situ hybridization (FISH), to compare the concordance of protein expression with gene amplification and to explore the optimization in process quality control.
METHODSA prospective study of invasive breast cancer specimens excised between May 2009 and April 2011 at the Cancer Hospital, Chinese Academy of Medical Sciences was conducted by automated IHC staining with the new 4B5 rabbit monoclonal antibody and FISH. An evaluation was performed according to the ASCO/CAP guidelines (2007) and Chinese guidelines (2009). The gene amplification status of 740 cases were detected by FISH.
RESULTSA total of 2420 cases of breast invasive ductal carcinoma without pre-operation therapy were tested by automated IHC. 551 cases (22.8%) were scored as positive (3+), 664 cases (27.4%) as equivocal (2+), and 1205 cases (49.8%) as negative (1+/0). Gene amplification was detected in 98.0% (242/247) HER2 protein expression positive (3+) cases and in 13.6% (53/389) equivocal (2+) cases. One of 247 (0.4%) HER2 expression 3+ cases and 5 of 389 (1.3%) HER2 expression 2+ cases were equivocal for gene amplification. No gene amplification was detected in expression negative (1+/0) cases by FISH (0/104). The overall concordance between IHC and FISH was 98.6% [(242 + 104)/(247 + 104)].
CONCLUSIONSThere is a high concordance rate between automated IHC with 4B5 rabbit monoclonal antibody and FISH results for assessing the HER2 gene amplification status in surgically-excised breast cancer specimens, suggesting that automated IHC with 4B5 antibody can provide a reliable method to detect HER2 overexpression for eligibility of HER2 targeted therapy.

OBJECTIVEThe aim of this study was to observe the association between the occurrence of esophageal cancer lesions and esophageal mucosa fold (white ridges), and further identify where is the initial origin of esophageal cancer lesions in the esophagus mucosa.
METHODSThis was a cohort study which recruited 551 subjects underwent endoscopic examination in a high risk area of esophageal cancer in Linxian, Henan Province in 1987. 339 subjects with esophageal white ridges, and with red area or erosion lesion at the surface of the white ridges, was studied as exposure group. Other 212 subjects whose esophagus had no white ridges and pathological diagnosis was negative, was studied as control group. The endpoint was occurrence of pathologically confirmed esophageal cancer. After a 15-year follow-up, the results were compared between two groups.
RESULTSAmong the 551 subjects, there were 339 cases with esophageal mucosal white ridges in the exposure group. During the period of 15 year follow-up, the incidence of esophageal cancer was 11.8% (9/76) in 76 case with simple mucosal white ridges, 33.5% (88/263) in 263 subjects with white ridges and red area, or erosions on the surface of white ridge. While only 8.0% of subjects (17/212) developed esophageal cancer after the 15-year follow up in the control group. There was a significant difference between the two groups (P < 0.001).
CONCLUSIONEsophageal mucosal white ridge, especially white ridge with red area or erosions is closely associated with subsequent esophageal cancer occurrence in the esophageal cancer high risk area in China. It is suggested that esophageal mucosa with white ridge may be the initial origin of esophageal cancer. Further investigations focused on this spot are required.
